- ETA International's catalog lists a 75% passing score on a 100-question, two-hour written EVT examination.
- The safety portion carries a separate 100% passing requirement, so a strong overall score cannot offset a missed safety question.
- A mandatory hands-on assessment sits alongside the written exam; the two-hour limit does not apply to it.
- Fee and retake details conflict between ETA's catalog (US$205) and ETA Press (US$200 with one free retake); confirm before booking.
What the EVT Passing Score Actually Is
The Electric Vehicle Technician (EVT) credential from ETA International (Electronics Technicians Association, International) is a stand-alone certification for maintenance, service, and troubleshooting of battery-electric vehicles. When candidates ask about the "passing score," they usually want one number. For EVT, there are really three things to understand: the overall written threshold, a separate safety threshold, and a hands-on assessment that is part of earning the credential.
According to ETA's currently linked Certification Catalog (undated cover, printed page 17), the written examination uses a 75% passing score. That same catalog entry lists 100 examination questions, a two-hour time allowance, and a separate 100% passing requirement for the safety portion. This article is built on those catalog figures. Where other sources disagree, we flag the conflict rather than blending numbers together.
If you are still orienting yourself on the credential itself, start with What Is EVT Certification? and then return here for the scoring mechanics.
The Two Thresholds: 75% Overall and 100% on Safety
The most important thing to grasp about EVT scoring is that it is not a single blended percentage. The catalog describes a general passing score of 75% and a separate, stricter standard for safety content. That structure reflects the job: high-voltage battery systems are unforgiving, and ETA treats safety knowledge as a pass-or-fail gate rather than something you can average away.
What does this mean in practice? Two candidates could each score above 75% on the general content, yet only the one who answers every safety question correctly meets the standard. For that reason, safety should be the first domain you master and the last one you review before test day. Our EVT difficulty guide explains why the safety gate is the part of this exam candidates most often underestimate.
What a 75% Looks Like on 100 Questions
Taking the catalog's 100-question figure at face value, a 75% passing score corresponds to 75 correct answers. That arithmetic is straightforward, but remember two caveats. First, the catalog does not break out how many of the 100 questions belong to the safety portion, so do not assume a specific split. Second, the historical format described in older ETA materials differs, which we cover below.
Format Behind the Score: Questions, Time, and Hands-On
The written component is only half of the credential. ETA's catalog lists a mandatory hands-on assessment, and ETA-approved schools administer both the written and hands-on components. The catalog's two-hour allowance describes the written examination only; it does not describe the practical assessment.
| Element | What ETA's Catalog Lists |
|---|---|
| Written questions | 100 |
| Written time allowance | Two hours |
| Overall passing score | 75% |
| Safety portion | 100% required, assessed separately |
| Hands-on assessment | Mandatory |
| Certification term | Four years |
| Listed fee | US$205 (conflicts with ETA Press; see below) |
Written testing is proctored by an ETA Certification Administrator, delivered either through Trapeza online testing or by paper and pencil. Trapeza scores are available immediately, which means you will know your written result before you leave the session. ETA's remote-proctoring page describes a service for non-hands-on certifications; it does not establish a fully remote path for EVT, so plan on in-person participation through an approved school.
Eligibility is its own topic. ETA states that CETa is not a prerequisite for the stand-alone pathway, and that specialized knowledge and hands-on training through an ETA-approved EV school are required. Our EVT requirements guide covers eligibility in detail.
Where Points Come From: The Ten Competency Categories
ETA's official competency document for the Electric Vehicle Technician (EVT), revision September 20, 2012 (copyright 2013), organizes examination content into ten categories of knowledge. ETA states that examination questions derive from the respective competencies. Critically, no percentage weights are published, so any claim that one domain is "worth" a specific share of your score is invented. The ten categories are:
Domain 1: Safety Requirements
The foundation of the 100% safety criterion.
- High-voltage hazard awareness and protective practices
- Safe shutdown and isolation of EV systems before service
- Personal protective equipment and safe work procedures
Domains 2 and 3: Electric Vehicle Fundamentals and Electrical Theory
The conceptual base for everything else.
- How a battery-electric vehicle differs from a conventional drivetrain
- Voltage, current, resistance, power, and circuit behavior
- Applying Ohm's-law-style reasoning to diagnostic problems
Domains 4, 5, and 6: Electronic Systems Components, Motor Theory, EV Electronics and Testing Fundamentals
Component knowledge plus the measurement skills to verify it.
- Recognizing and understanding electronic components in EV systems
- Electric motor operating principles as used for propulsion
- Test equipment, measurement technique, and interpreting readings
Domains 7, 8, and 9: Batteries, Energy Delivery Systems, and Charging
The heart of battery and power-electronics diagnostics.
- Battery construction, behavior, and handling
- How energy moves from storage to the drive system
- Charging concepts and equipment
Domain 10: BEV Maintenance and Troubleshooting
Where theory meets the service bay.
- Systematic diagnostic approach to battery-electric vehicles
- Routine maintenance tasks and inspection logic
For a deeper walk through each area, see the complete guide to all ten EVT content areas. One important dating note: the competency document's revision date and its historical NFPA/NEC reading editions should not be treated as a 2026 syllabus revision. The domain list is the official one, but it is not a newly updated 2026 standard.
Conflicting Figures You Will Find Online
Searching for EVT scoring details turns up inconsistent numbers, and mixing them produces a wrong picture. Here are the two conflicts that matter most.
Fee and Retake Conflict
ETA's Certification Catalog lists a fee of US$205. ETA Press's separately published EVT listing gives US$200 and states that one free retake is available after a 30-day wait, within one year of the first examination. Both are ETA-affiliated sources, and we cannot tell you which governs your specific booking. Confirm the current fee and retake conditions with ETA or your approved school before paying. Our EVT certification cost breakdown lays out the budget implications.
Historical Format Conflict
An ETA program update dated December 5, 2012, described 75 knowledge questions, 30 separate safety questions, and 46 practical tasks. That is a different structure from the catalog's 100-question figure. Do not combine these counts. Treat the 2012 numbers as historical context, and do not treat "46 tasks" as a verified current practical-assessment count.
Test-Day Rules That Affect Your Result
Scoring rules matter less if a procedural slip derails your session. ETA's testing rules include the following:
- Photo identification is required. Bring valid photo ID.
- Calculator: a non-programmable scientific calculator is permitted. Practice with the exact model you will bring.
- Scratch paper: permitted, but used scratch paper must be surrendered at the end.
- Phones are prohibited.
- Proctoring: an ETA Certification Administrator oversees the written exam, via Trapeza online testing or paper and pencil.
Because Trapeza scores are available immediately, you will see whether you cleared the threshold right away. If you test on paper, ask your administrator how and when results are reported.
Retakes, Fees, and What a Fail Costs You
A miss on either threshold, the 75% overall score or the 100% safety requirement, means you have not passed the written component. The ETA Press listing describes one free retake after a 30-day wait within one year of the first examination, but the catalog does not repeat that policy, so verify it before relying on it. Also confirm whether your approved school charges separately for hands-on sessions or retakes of the practical portion.
Because a safety miss is disqualifying even with a high overall score, the most cost-effective preparation is to drill safety content until errors are rare. Practice questions mapped to each category help you find weak spots before you pay for a sitting; you can try them on the EVT Exam Prep practice test site.
After You Pass: Term and Maintenance
The catalog lists a four-year certification term. Maintenance with Hands-On requires:
- Six continuing-education contact hours per year, totaling 24 over four years
- A supervisor-completed Employer Verification Form
- The Certification Maintenance Form
- US$25 per year, totaling US$100 over the four-year cycle
Whether the credential pays off for you depends on your local market and employer. Earnings data tied to the occupation is not the same as an EVT-specific pay premium, which is unverified. See the EVT salary guide and the ROI analysis for how to think about that distinction.
Scheduling Prep Around the Scoring Rules
Since safety is a 100% gate and the other nine categories feed the 75% overall score, sequence your preparation to protect the gate first. A sample arrangement, to be adjusted to your training calendar:
Safety Requirements first
- Work Domain 1 until you can explain each procedure, not just recognize it
- Re-test safety content again at the end of every later week
Fundamentals and theory
- Domains 2 and 3: EV fundamentals and electrical theory
- Practice calculations with your permitted scientific calculator
Components, motors, and testing
- Domains 4, 5, and 6 together, since measurement ties them to the earlier theory
Batteries, energy delivery, charging
- Domains 7, 8, and 9 as a connected power chain
Troubleshooting and full review
- Domain 10 scenarios, then mixed practice and a final safety pass
For a fuller plan, read the EVT study guide, and keep the EVT cheat sheet handy for last-minute review. If you are also weighing credentials, note that ASE L3 is a separate certification with its own eligibility and scope; compare them using ASE's Light Duty Hybrid/Electric Vehicle Specialist test page rather than assuming the scoring rules carry over.
Key Takeaway
Treat the exam as two separate targets: 75% overall and 100% on safety. Do not rely on any domain-weight claims, because ETA publishes none. Cover all ten categories, and verify fee, retake, and hands-on details with ETA or your approved school before booking.
Frequently Asked Questions
ETA's Certification Catalog lists a 75% passing score for the written examination, with a separate 100% passing requirement for the safety portion. The catalog also lists 100 questions and a two-hour time allowance.
According to the catalog, the safety portion has its own 100% passing requirement, so a high overall score does not offset missed safety questions. Confirm the exact handling with ETA or your approved school.
No. The two-hour allowance describes the written examination. The hands-on assessment is mandatory and separate, and the catalog's time figure does not describe it.
ETA's catalog lists US$205, while ETA Press lists US$200 and mentions one free retake after a 30-day wait within one year of the first exam. These sources conflict, so confirm the current fee and retake terms with ETA before booking. See our cost breakdown for more.
ETA does not publish percentage weights for the ten competency categories in its competency document, and we do not cite an EVT pass rate here. For a discussion of what data is and is not available, see EVT Pass Rate 2026: What the Data Shows.
